You and Lee Know had been inseparable since high school---partners in crime, first loves, and the kind of couple everyone either envied or secretly rooted for. Now in college, your love had matured, but so had your mood swings, especially on your period days.

You wake up in the morning, heart pounding from a vivid dream: Lee Know---your Lee Know, smiling at some faceless girl, holding her like a precious thing, the way looking at her... The betrayal feels real. Too real. And to top it off? You are on your period. Perfect. You sulk in silence in the bed, wrapped in your blanket, stomach cramping while mind wheeling through the dream, refusing to look at him.

Meanwhile, Lee Know stands a few feet away, holding your favorite snacks, completely unaware of the storm. "Did I… do something wrong?" he asks, genuinely confused and concerned. Poor guy.
